JOHN H. DE VALIN, BALTIMORE, MARYLAND.

IMPROVEMENT IN AXLES.

Speoication forming part of Letters Patent No. 181,647, dated August 29,1876; application filed August 12,1876.

To all whom it may concern:

Be it known that I, JOHN H. DE VALIN, of

the city of Baltimore and State of Maryland, have invented certainImprovements in Axles, of which the following is a speeication and I dohereby declare that in the same is contained a full, clear, and exactdescription of my said invention, reference being had to the accompanying drawing and to the letters of reference marked thereon.

. This invention relates to an axle, the distnguishing features whereofconsistv in that the arms or parts of the axle upon which the wheelsrevolve are constructed to be readily detached from the main portion orbody or' the same, and adapted to be vertically adjustable withreference to the said body of the axle and the Vehicle to which it isconnected.

In the description of an axle embodying my improvements, which follows,due reference must be had to the accompanying drawing, forming a part ofthis specification, and in which- Figure 1 is a side View of theimproved axle, partly in section; Fig. 2, a top view of the same; Fig.3, a cross section of the axle, on line x y, and Fig. 4 a side view ofparts of the axle, modified in construction.

Similar letters of reference indicate similar parts in all the figures.

A is the main portion or body of the axle, and B the arms, connected tothe body in such manner as to be easily and readily detached therefrom.To admit of this detachment the arms are provided With the shanks a,which are inserted in the sockets b in the ends of the body, and securedby means of the nut and washers, represented respectively by c and d.The adjustability of the arms B is obtained by constructing the shanksand sockets of such relative widths as will admit of a vibratorymovement of the arms, and by removing a portion ofthe web of the body,to allow of a corresponding movement of the the said nuts having fixedpositions with reference to the body of the axle.

The arms being detachable, their replacement, when broken or bent, 4isreadily accomplished, and that Without interference with the connectionbetween the body of the axle and the'vehicle, while the adjustabilityofthe arms admits of their being set to give the required swing to theWheels. y

Having thus described my invention, Iwhat I claim as new, and wish tosecure by Letters Patent of 'the United States, is-

1. The detachable arm B, combined with' the body A of the axle in suchmanner as to admit of its vertical adjustment with reference to thelongitudinal center line of the said axle, substantially as shown.

2. In combination with the arms B, having the shanks a projectingtherefrom, and body A, socketed at the ends thereof, as shown, thewashers d and nuts c, the said washers and body having their opposingsurfaces provided with teeth or serrations, substantially as and for thepurpose set forth.

In testimony whereof I have hereunto subscribed my name this 10th day ofAugust, A. D. 187
